Hi Arunprasad,
Thanks for your tips. My environment as following: CPU: SH4; SVN revision: 65000 OS: WINCE Tool Chain: MSVS+PB JS test case: I cann’t get the single js test case. But I can reproduce it as this steps[First access the http://image.baidu.com/, then access http://maps.google.de, wait 2-5 minitues, it will crash. The crash type is “access violation”]. I have try to debug it, find that the crash was caused by the jit, if we disable the JIT feature, the browser will not crash. As the test case is very complex and it is hard to be simplify, so I don’t know how to debug it. I try to print all the emitted instructions, but it is too many for me to analyze, after the instructions were emitted, the instruction will be repatch or relink, so anybody can give me some suggestion for how to debug it. Thanks.
